Im uploading my pc and i was wondering if I'll need to update the bios im getting a gigabyte aorus elite x570 and ryzen 3600x will that motherboard work out of the box with a 3600x
Yes, every X570 motherboard ships with a Ryzen 3000 compatible BIOS.
Should i update the bios even if im not very comfortable with doing that yet?What that means is it should POST and go into the BIOS setup straight out of the box. But the BIOS and AGESA are continuing to evolve, so you'll want to update the BIOS to the newest version and periodically check for updates.
I dont know anyone else who knows computers is it 100% necessary to update?Yes, when newer BIOS versions get released that improve performance and/or stability you should update your BIOS.
If you are not confident that you can do that, then you should ask someone you trust to do it correctly to do it for you.
